A heat pump is a device that uses work to transfer heat from a cool space to a warm space by transferring thermal energy using a refrigeration cycle, cooling the cool space and warming the warm space. In cold weather, a heat pump can move heat from the cool outdoors to warm a house; the pump may also be designed to move heat from the house to the warmer outdoors in warm weather. As they transfer heat rather than generating heat, they are more energy-efficient than other ways of heating or cooling a home.
Eco-capitalism, also known as environmental capitalism or (sometimes) green capitalism, is the view that capital exists in nature as "natural capital" on which all wealth depends. Therefore, governments should use market-based policy-instruments to resolve environmental problems.
A green economy is an economy that aims at reducing environmental risks and ecological scarcities, and that aims for sustainable development without degrading the environment. It is closely related with ecological economics, but has a more politically applied focus. The 2011 UNEP Green Economy Report argues "that to be green, an economy must not only be efficient, but also fair. Fairness implies recognizing global and country level equity dimensions, particularly in assuring a Just Transition to an economy that is low-carbon, resource efficient, and socially inclusive."
Green building refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throughout a building's life-cycle: from planning to design, construction, operation, maintenance, renovation, and demolition. This requires close cooperation of the contractor, the architects, the engineers, and the client at all project stages. The Green Building practice expands and complements the classical building design concerns of economy, utility, durability, and comfort. Green building also refers to saving resources to the maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature. Buildings that live in harmony; green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.’
Environmental technology (envirotech) is the use of engineering and technological approaches to understand and address issues that affect the environment with the aim of fostering environmental improvement. It involves the application of science and technology in the process of addressing environmental challenges through environmental conservation and the mitigation of human impact to the environment.
Environmental consulting is often a form of compliance consulting, in which the consultant ensures that the client maintains an appropriate measure of compliance with environmental regulations. Sustainable consulting is a specialized field that offers guidance and solutions for businesses seeking to operate in an environmentally responsible and sustainable way. The goal of sustainable consulting is to help organizations reduce their environmental impact while maintaining profitability and social responsibility. There are many types of environmental consultants, but the two main groups are those who enter the field from the industry side, and those who enter the field from the environmentalist side.
Business action on climate change includes a range of activities relating to climate change, and to influencing political decisions on climate change-related regulation, such as the Kyoto Protocol. Major multinationals have played and to some extent continue to play a significant role in the politics of climate change, especially in the United States, through lobbying of government and funding of climate change deniers. Business also plays a key role in the mitigation of climate change, through decisions to invest in researching and implementing new energy technologies and energy efficiency measures.
An eco-city or ecocity is "a human settlement modeled on the self-sustaining resilient structure and function of natural ecosystems", as defined by Ecocity Builders. Simply put, an eco-city is an ecologically healthy city. The World Bank defines eco-cities as "cities that enhance the well-being of citizens and society through integrated urban planning and management that harness the benefits of ecological systems and protect and nurture these assets for future generations". Although there is no universally accepted definition of an 'eco-city', among available definitions, there is some consensus on the basic features of an eco-city.
Clean technology, also called cleantech or climatetech, is any process, product, or service that reduces negative environmental impacts through significant energy efficiency improvements, the sustainable use of resources, or environmental protection activities. Clean technology includes a broad range of technology related to recycling, renewable energy, information technology, green transportation, electric motors, green chemistry, lighting, grey water, and more. Environmental finance is a method by which new clean technology projects can obtain financing through the generation of carbon credits. A project that is developed with concern for climate change mitigation is also known as a carbon project.
A sustainable city, eco-city, or green city is a city designed with consideration for social, economic, environmental impact, and resilient habitat for existing populations, without compromising the ability of future generations to experience the same. The UN Sustainable Development Goal 11 defines sustainable cities as those that are dedicated to achieving green sustainability, social sustainability and economic sustainability. They are committed to doing so by enabling opportunities for all through a design focused on inclusivity as well as maintaining a sustainable economic growth. The focus will also includes minimizing required inputs of energy, water, and food, and drastically reducing waste, output of heat, air pollution – CO2, methane, and water pollution. Richard Register, a visual artist, first coined the term ecocity in his 1987 book Ecocity Berkeley: Building Cities for a Healthy Future, where he offers innovative city planning solutions that would work anywhere. Other leading figures who envisioned sustainable cities are architect Paul F Downton, who later founded the company Ecopolis Pty Ltd, as well as authors Timothy Beatley and Steffen Lehmann, who have written extensively on the subject. The field of industrial ecology is sometimes used in planning these cities.
The CDP is an international non-profit organisation based in the United Kingdom, Japan, India, China, Germany, Brazil and the United States that helps companies, cities, states, regions and public authorities disclose their environmental impact. It aims to make environmental reporting and risk management a business norm, driving disclosure, insight, and action towards a sustainable economy. In 2022, nearly 18,700 organizations disclosed their environmental information through CDP.
Sustainable Silicon Valley (SSV) is a collaboration of businesses, governments, and non-governmental organizations that are identifying and addressing environmental and resource pressures in Silicon Valley. As its first initiative, SSV engaged Valley organizations, who are the SSV Partners, to work towards a goal of reducing regional carbon dioxide (CO2) emissions 20% below 1990 levels by 2010. The SSV approach to reaching this goal is to facilitate strategies to reduce CO2 emissions through increased energy and fuel efficiency and through the use of renewable sources of energy.

A zero-carbon city is a goal of city planners that can be variously defined. In a narrower sense of energy production and use, a zero-carbon city is one that generates as much or more carbon-free sustainable energy as it uses. In a broader sense of managing greenhouse gas emissions, a zero-carbon city is one that reduces its carbon footprint to a minimum by using renewable energy sources; reducing all types of carbon emissions through efficient urban design, technology use and lifestyle changes; and balancing any remaining emissions through carbon sequestration. Since the supply chains of a city stretch far beyond its borders, Princeton University's High Meadows Environmental Institute suggests using a transboundary definition of a net-zero carbon city as "one that has net-zero carbon infrastructure and food provisioning systems".
Eco-investing or green investing is a form of socially responsible investing where investments are made in companies that support or provide environmentally friendly products and practices. These companies encourage new technologies that support the transition from carbon dependence to more sustainable alternatives. Green finance is "any structured financial activity that has been created to ensure a better environmental outcome."
Green urbanism has been defined as the practice of creating communities beneficial to humans and the environment. According to Timothy Beatley, it is an attempt to shape more sustainable places, communities and lifestyles, and consume less of the world's resources. Urban areas are able to lay the groundwork of how environmentally integrated and sustainable city planning can both provide and improve environmental benefits on the local, national, and international levels. Green urbanism is interdisciplinary, combining the collaboration of landscape architects, engineers, urban planners, ecologists, transport planners, physicists, psychologists, sociologists, economists and other specialists in addition to architects and urban designers.
"Sustainability," was defined as “development which implies meeting the needs of the present without compromising the ability of future generations to meet their own needs”as defined by the 1983 Brundtland Commission. As sustainability gains support and momentum worldwide, universities across the United States have expanded initiatives towards more sustainable campuses, commitments, academic offerings, and student engagement.
The Sustainability Accounting Standards Board (SASB) is a non-profit organization, founded in 2011 by Jean Rogers to develop sustainability accounting standards. Investors, lenders, insurance underwriters, and other providers of financial capital are increasingly attuned to the impact of environmental, social, and governance (ESG) factors on the financial performance of companies, driving the need for standardized reporting of ESG data. Just as the International Accounting Standards Board (IASB) and the Financial Accounting Standards Board (FASB) have established International Financial Reporting Standards and Generally Accepted Accounting Principles (GAAP), respectively, which are currently used in the financial statements, SASB's stated mission “is to establish industry-specific disclosure standards across ESG topics that facilitate communication between companies and investors about financially material, decision-useful information. Such information should be relevant, reliable and comparable across companies on a global basis.”
The Climate Disclosure Standards Board (CDSB) is a non-profit organization working to provide material information for investors and financial markets through the integration of climate change-related information into mainstream financial reporting. CDSB operates on the premise that investors and financial institutions can make better and informed decisions if companies are open, transparent and analyse the risks and opportunities associated with climate change-related information. To this end, CDSB acts as a forum for collaboration on how existing standards and practices can be used to link financial and climate change-related information using its Framework for reporting environmental information, natural capital and associated business impacts.
Sustainable finance is the set of practices, standards, norms, regulations and products that pursue financial returns alongside environmental and/or social objectives. It is sometimes used interchangeably with Environmental, Social & Governance (ESG) investing. However, many distinguish between ESG integration for better risk-adjusted returns and a broader field of sustainable finance that also includes impact investing, social finance and ethical investing.
